JAMES TAYLOR PLUMER, OF PONTIAC, MICHIGAN.

SPRAYER.

Patented Apr. 1, 1919.

Application filed September 25, 1917. Serial No. 193,110.

To all whom it may concern Be it known that I, J AMES T. PLUMER, a citizen of the United States, and a resident of Pontiac, in the county of Oakland and State of Michigan, have invented a new and Improved Sprayer; of which the following is a. full, clear, and exact description.

My invention relates more particularly to apparatus adapted to spray a comparatively large area through the medium of sprayer arms.

- An object of the invention is to provide a spraying apparatus of the character indicated improved with respect to the frame which is adapted to be adjusted to suit various widths of rows of plants, and having spraying means including a stand pipe so supported in the frame as to be revoluble and to be adjustable with the adjustment of the frame toma-intain the stand pipe ap- An important object of the invention also is to provide an improved jet of very simple form to control with facility the discharge of the water from the outlet orifices inthe spraying arms or to entirely out off the flow. Other objects of the invention and the "advantages of my improved construction will appear as the description proceeds.

Reference'is to be had to the accompanying drawings forming a part of this specification in which similar reference characters indicate corresponding parts in all the views, it being understood that the drawings are merely illustrative of one example of the invention.

Fig. 2 is a side elevation thereof witli parts broken away and others in section;

Fig. 3 is a partial vertical section on an enlarged scale; 7

. Fig. 4 is a fragmentary planview on an enlarged scale given to show adjustable means for anchoring the stand pipe to a Fig. 5 is a plan view of the superstructure from which guys run to the distributing arms;

'Fig. '6is afragmentary plan view of the lower portion of the superstructure on the the guys;

Fig. 7 is a cross section through the stand standpip'e showing the winding drums for Fig. 8 is an enlarged cross sectional view of one of the distributing arms and an adjustable jet therein;

Fig. 9 is a fragmentary longitudinal section of one of the distributing arms;

Fig. 10 is a detail in horizontal section on the line 10-10, Fig. 3.

In the illustrated embodiment of my invention side frames designated generally by the numeral 10 are provided adapted to be disposed at varying angles to each other. Each frame is provided with a suitable shoe 11 to facilitate the hauling of the frame and the supported; spraying means, by connecting the frame members with suitable hauling means (not shown) or draft animals. In the illustrated frame a suitable number of bars 12 extend upwardly from the shoes 11, and'various brace members 13 are employed. 9

In order to pivotally connect the upper ends of the frames 1.0 longitudinal shaft-s or rods 14 are employed which pass through any suitable members on the upper ends of the bars 12, there being shown for the purpose, (see Fig. 1) brackets 12 on said bars 12 through which the rods 14 pass. ner ends of the rods 14 pass through a saddle 'ring 15 to which the rods are swiveled at plate to have universal movement.

A stand pipe 19 receives a supply of water in the manner hereinafter described and said stand pipe extends freely through a central opening 18 in the saddle plate 16.

To the stand pipe is secured a distributing head 21, the base 20 of which isrevolublc on the saddle plate 16, the said base 20 and the saddleplate jointly forming a ball race for ball bearings 22. The head 21 has ra dially disposed nipples 23 to which distributing arms 24 are secured preferably by a suitable flexible connection, there being shown short lengths of hose indicated at 25 which permit the arms 24 to have yarious angular positions relatively to thenipples 28. The distributing arms 24 are equipped with jets The in' 26 hereinafter more particularly referred to. To strengthen the flexible connection between the arms 24 and nipples 23 I may employ yokes 25 best seen in Figs. 1, 3 and 8, each of which presents side arms pivoted as at 21 to a nipple 23 and the opposite end suitably secured to the inner end of the adjacent distributing arm 24. In the example shown (see Fig. 8) a flanged nipple 25" is secured by rivets or bolts 24 to the flange 24 of the distributing arm, said nipple 25 receiving the adjacent end of the hose section 25.

To supply water to the stand pipe 19 the lower end of said stand pipe is revoluble in a receiving head designated generally by the numeral 27, here shown as having nip ples 28 to either of which a water supply pipe or hose 29 is connected, the opposite nipple usually being capped as at 28. On the receiving head 27 is a stufling box 30 and above the said stuffing box a bearing collar 31 around the stand pipe is provided with suitable bearing elements such as rollers 32. A collar 38 may be provided on the stand pipe 19 to constitute a rest for the collar 31. The collar 31 and stufling box 30 are suitably suspended trom the saddle plate 16, there being shown for the purpose rods 33 fastened in any desired way to the said saddle plate and secured at their lower ends to the bearing collar 31. Other hanger rods 34 suspend the stuffing box 30 from the collar 31. The stuffing box may include a flange 35 secured to the flange 36 of the stuffing box as by bolts 34. If desired, a collar 37 (Fig. 3) may be formed on or secured to the lower end of the stand pipe 19 to prevent the possibility of the stand pipe rising under the pressure of the water.

To adjustably anchor the collar 31 with a side 10 of the frame I employ a brace arm 39 and brace arms 40' at the sides of the arm 39, said arms being pivoted at their inner ends to the collar 31 and adjustably connected at their outer ends with a short longitudinal anchor bar 41 on the adjacent frame 10. The brace arm 39 hasa slot and pin connection with the bar 41, there being a slot 42 in said brace arm, and a pin or bolt 43 extends through said slot and into a block 44 disposed between the side 1nembers of the bar 41. Any suitable nut 43 or the like serves to tighten the bolt 43 to hold the arm 39 and block 44 in a given adjustment. To slidably and pivotally connect the outer ends of the arms 40 with the bar 41 in the illustrated example, upper and lower plates 45 are slidable on the said bar and receive bolts 46, said bolts passing also through blocks 47 disposed in pairs between the side members of the said bar 41. Between the blocks 47 of a pair a toothed pinion 49 is disposed and meshes with fixed rack 48 on a side of the bar 41, each pinion being secured to a pin or shaft 50, the upper end of which is square to receive a wrench as indicated at the bottom of Fig. 4, whereby to turn the pinions 49 causing the plates 45 and the outer ends of the brace arn1s'40 to travel longitudinally of the bar 44 whereby to adjust the collar '31 for permitting the stand pipe 19 to maintain an approximately vertical position as when the side frames 10 are on a hillside or inclined ground, for example.

As seen best in Figs. 8 and 9 each jet 26 is tapped into a side of a distributing arm 24. Each jet is threaded externally to engage threads in a jet orifice of the distributmg arm and is formed with a longitudinal groove 52 of gradually increasing depth toward the inner end. Preferably the jet is offset to provide a handle member 26 at the outer end for turning it. By screwing the jet more or less into the distributing arm 24, the groove 52 will regulate the flow of water to the jet or the flow may be entirely out ofi by turning the jet until its cylindrical threaded portion eflects a closure of the jet orifice.

Supported on the upper end of the stand pipe 19 and its distributing head 23 is a superstructure designated generally by the number 53 and including a tubular central iember 54 flanged at its lower end and bolted as at 55 to the top of the head 23 in line with the stand pipe 19 to constitute in effect a continuation of the distributing head 23, the upper end of the tube 54 being capped or otherwise closed so as to act in a measure as an air chamber to contribute to maintaining a regular supply of water to the supply arms 24. Guys 56 extend from the superstructure 53 to the distributing arms 24 at various points along the same. Said guys are connected with winding means to wind in or pay out the same to dispose the distributing arms at different angles for which purpose I have illustrated drums 57 on the superstructure 53 at the bottom, the shafts of the drums being squared to receive a crank handle 58 and the drums having ratchet wheels 59 engaged by pawls 60. From the drums 57the guys extend to the top of the superstructure 53 and pass over sheaves 61 from which the guys extend tothe arms 24 to which they are made fast in any suitable manner. I may employ additional guys 62 secured at their inner ends'to Outriggers 63 on the top of the superstructure 53 and secured at the outer ends to the outer ends of the distribut ing arms 24 to limit the downward movement of said arms. In Fig. 1 the character 26 indicates an end jet on an arm 24, said end jet corresponding with the jets 26.

The jets 26 are all disposed on the respective arms 24 in a similar direction so that the reaction may tend to turn the spraying in Fig. 1. 7

To strengthen the stand pipe 19 I insert a core therein designated by the numeral 6i and presenting radially disposed webs bearing against the inner surface of the stand pipe and dividing the same into chambers. The said stiffening core projects above the stand pipe 19 through the distributing head 21 and into the tube 54.

The side frames 10 are equipped with suitable means to hold the same in'adjusted position, there being indicated transverse latch bars 65 pivoted at one end as at 66 to a longitudinal bar 1O on one frame 10, the opposite end of each latch bar being adapted to be secured by a pin 67 to the similar longitudinal bar 10 of the other frame 10, there being provided a longitudinal series of holes in the latch bar as indicated at 68., Fig. 1,

either of which holes may receive the pin 67.

I wish to state in conclusion that although the illustrated example constitutes a ractical embodiment of my invention, I 0 not limit myself strictly to the mechanical details herein illustrated, since manifestly the same can be considerably varied without departure from the spirit of the invention as defined in the appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
